丹戎布拉大学师范教育学院汉语专业 2019 届学生对动词 “穿”、“戴”与“用”的掌握情况分析

AbstractThe three common verbs in Chinese are “chuan”, “dai” and “yong”. They have the same semantics but different specific usages. Therefore, Chinese learners often misuse these three words. In order to understand the mastery condition and analyse the difficulties of students on using the verbs of “chuan”, “dai” and "yong” on the Chinese Language students of Tanjungpura University in academic year 2019, the author used a test method to examine student and analyses the difficulties of “chuan”, “dai” and “yong”. The test results show that the percentage of correct answers for the word “chuan” is 48,42%, the percentage of correct answers for the word “dai” is 57,84% and the percentage of correct answers for the word “yong” is 62,83%. From the results obtained by the author, we can know that they have a better grasp of “yong” and “dai” than “chuan”.Keywords: Verbs, “chuan”, “dai” and “yong”, The Condition of Master

Physical Activity and Cognition in Older Adults: The Potential of Tai Chi Chuan

The purpose of this article is to review the potential of Tai Chi Chuan as a mode of physical activity that could have cognitive benefits for older adults and to provide potential directions for future research. A brief introduction to Tai Chi Chuan and its related physical benefits is provided. In addition, the empirical literature related to Tai Chi Chuan and cognition is reviewed. Potential mediators of the relationship between Tai Chi Chuan and cognition, including physical resources, disease status, and mental resources, are discussed. Based on the limitations of the extant literature, it is argued that future research in this area must provide more detailed descriptions of Tai Chi Chuan, particularly in terms of intensity and program progression. Consideration of the specific type of cognition that is expected to benefit is also encouraged, and approaches for further efforts to understand how Tai Chi Chuan affects cognition are recommended

Analysis of static and dynamic balance in healthy elderly practitioners of Tai Chi Chuan versus ballroom dancing

OBJECTIVE: To determine whether Tai Chi Chuan or ballroom dancing promotes better performance with respect to postural balance, gait, and postural transfer among elderly people. METHODS: We evaluated 76 elderly individuals who were divided into two groups: the Tai Chi Chuan Group and the Dance Group. The subjects were tested using the NeuroCom Balance Master¯ force platform system with the following protocols: static balance tests (the Modified Clinical Tests of Sensory Interaction on Balance and Unilateral Stance) and dynamic balance tests (the Walk Across Test and Sit-to-stand Transfer Test). RESULTS: In the Modified Clinical Test of Sensory Interaction on Balance, the Tai Chi Chuan Group presented a lower sway velocity on a firm surface with open and closed eyes, as well as on a foam surface with closed eyes. In the Modified Clinical Test of Sensory Interaction on Unilateral Stance, the Tai Chi Chuan Group presented a lower sway velocity with open eyes, whereas the Dance Group presented a lower sway velocity with closed eyes. In the Walk Across Test, the Tai Chi Chuan Group presented faster walking speeds than those of the Dance Group. In the Sit-to-stand Transfer Test, the Tai Chi Chuan Group presented shorter transfer times from the sitting to the standing position, with less sway in the final standing position. CONCLUSION: The elderly individuals who practiced Tai Chi Chuan had better bilateral balance with eyes open on both types of surfaces compared with the Dance Group. The Dance Group had better unilateral postural balance with eyes closed. The Tai Chi Chuan Group had faster walking speeds, shorter transfer times, and better postural balance in the final standing position during the Sit-to-stand Test

ELECTROMYOGRAPHIC ANALYSIS OF TAI CHI CHUAN: A PILOT STUDY

This investigation determined the electromyographical characteristic of the Tai Chi Chuan. An experienced Tai Chi Chuan Master was asked to perform the basic movements of Ward off, Roll Back, Press and Push. Both “gentle practising mode” and “strenuous defense mode” were performed. The Push movement was used for data analysis. The results revealed that the large muscle groups of the entire body were activated during Tai Chi Chuan. In most of the time, the work of muscles was quite low in both modes. However, it could generate a peak electromyographic activity as high as the fourth times of the maximal voluntary contraction in the ”strenuous defense mode”. It’s ability for defense combat shouldn’t be neglected. The results also demonstrated that Tai Chi Chuan involves the work of muscles of the trunk and the lower limbs greater than the upper limbs

THE KINEMATICAL CHARACTERISTICS OF THE LOWER EXTREMITIES DURING TAl CHI CHUAN EXERCISE

There is broad consensus that Tai Chi Chuan exercise can improve the balance control and muscle strength of the lower extremities. However, the mechanism used to promote that balance control and muscle strength is still unclear. The purpose of this study is to provide evidence of the kinematical characteristics of the lower extremities during Tai Chi Chuan exercise and explain the way in which they benefit balance control and muscle strength A female elite Tai Chi Chuan master was recruited to participate in the study. Five typical movements were selected: Brush Knee and Twist Steps, Step Back to Repulse Monkey, Wave Hand in Cloud, Kick Heel to Right, and Grasping the Bird's Tail. For each typical movement, three trials were recorded and digitized with a video motion analysis system. Kinematical parameters including the step length, the base of gait, angle of gait, mean ankle complex flexion, range of motion, range of motion rotation, and mean knee flexion, range of motion were calculated and analyzed. The results showed that compared to the normal gait, Tai Chi Chuan movements had a longer step length, a wider base of gait, and a larger angle of gait. The small angles and large range of motion existed in both the ankle complex and the knee joint. These kinematical characteristics may help to maintain stable posture and improve the muscle strength of the lower extremities during the performance of Tai Chi Chuan exercise

The effect of Tai Chi Chuan in reducing falls among elderly people: design of a randomized clinical trial in the Netherlands [ISRCTN98840266]

BACKGROUND: Falls are a significant public health problem. Thirty to fifty percent of the elderly of 65 years and older fall each year. Falls are the most common type of accident in this age group and can result in fractures and subsequent disabilities, increased fear of falling, social isolation, decreased mobility, and even an increased mortality. Several forms of exercise have been associated with a reduced risk of falling and with a wide range of physiological as well as psychosocial health benefits. Tai Chi Chuan seems to be the most promising form of exercise in the elderly, but the evidence is still controversial. In this article the design of a randomized clinical trial is presented. The trial evaluates the effect of Tai Chi Chuan on fall prevention and physical and psychological function in older adults. METHODS/DESIGN: 270 people of seventy years and older living at home will be identified in the files of the participating general practitioners. People will be asked to participate when meeting the following inclusion criteria: have experienced a fall in the preceding year or suffer from two of the following risk factors: disturbed balance, mobility problems, dizziness, or the use of benzodiazepines or diuretics. People will be randomly allocated to either the Tai Chi Chuan group (13 weeks, twice a week) or the no treatment control group. The primary outcome measure is the number of new falls, measured with a diary. The secondary outcome measures are balance, fear of falling, blood pressure, heart rate, lung function parameters, physical activity, functional status, quality of life, mental health, use of walking devices, medication, use of health care services, adjustments to the house, severity of fall incidents and subsequent injuries. Process parameters will be measured to evaluate the Tai Chi Chuan intervention. A cost-effectiveness analysis will be carried out alongside the evaluation of the clinical results. Follow-up measurements will be collected at 3, 6 and 12 months after randomization. DISCUSSION: As far as we know this is the first trial in Europe considering Tai Chi Chuan and fall prevention. This project will answer a pragmatic research question regarding the efficacy of Tai Chi Chuan regarding fall reduction

BIOMECHANICAL ANALYSIS OF TAI CHI CHUAN FIXED-STEP PUSH-HAND

Tai Chi Chuan is a Chinese traditional martial art. It is not only helpful to health (Frye, Scheinthal, Kemarskaya, and Pruchno, 2007) but also a fighting skill. After routine training for a long time, Tai Chi Chuan learners will do an advance sparring set training, that is, Push-hand. They are trained to use their tactile sense well and apply the ‘Eight Methods of Tai Chi’ to attack and defend in reality (Wu, 1994) in Push-hand process. Chan, Luk, & Hong (2003) revealed the kinematic characters while a master performing the push movement in Tai Chi. Most of the principles of Push-Hand were only recorded in Tai Chi Chuan ancient books and records. Consequently, the purpose of this study was to identify biomechanical characters in Push-hand process and to expound it scientifically
